According to the elasTc rebound hypothesis, most earthquakes are produced by the rapid release of energy stored in rock that has been subjected to great forces. When the strength of the rock is exceeded, it suddenly breaks, releasing some of its stored energy as seismic waves. AFershocks and Â±oreshocks Even a great earthquake like the 1906 San Francisco earthquake usually does not release all the elasTc energy stored in the rock along a fault.
What Aircraft Require a Type Rating? In general, the FAA requires a type rating for all aircraft with a maximum certified gross takeoff weight exceeding 12,500 lbs and for all turbojet (jet) aircraft, regardless of weight. Other aircraft types require a type rating as determined by the FAA.
LEED is flexible enough to apply to all project types. Each rating system groups requirements that address the unique needs of building and project types on their path towards LEED certification.Once a project team chooses a rating system, theyâll use the appropriate credits to guide design and operational decisions.he key to success is making sure you're using the right tools. LEED v4 is backed by a supporting cast of tools and resources. 1  Discover which LEED v4 rating system applies to your project. 2  Get started.
